Ken Levine writing new game

BioShock designer and Irrational Games cofounder Ken Levine is writing a new game.

"Game writing this afternoon. This is something else," Levine said on Twitter today.

Asked by a Twitter user what he looks to for inspiration, Levine called out period drama Mad Men, as well as the work of film directors Paul Thomas Anderson (There Will Be Blood,) the Coen brothers (No Country for Old Men) Stanley Kubrick (Full Metal Jacket), and Steven Soderbergh (Ocean's 11).

Levine also said he is inspired by the work of British playwright and film writer Tom Stoppard (Brazil), as well as composer Stephen Sondheim (Sweeney Todd).

On the eve of BioShock Infinite's launch in March, Levine said he had no idea what Irrational Games would create next.

"I don't have a thought for our next game, so it's kind of hard to even think about that," he said at the time.

Irrational Games currently lists 17 open positions on its website running the gamut of development. However, some appear to be outdated, as a requisition for level designer states the studio's current project is BioShock Infinite.
